' -1 Claim. (014299-38 My invention relates to atomizers for liquids,munication with'the shell 32. To the upper end such as perfume andthelike, and has among its of the tube 36 adjacent the side thereof Isecure objects and advantages the provision of a simple a shorttube 44which extends: through the wall and efficient atomizer of suchproportions as to area depression 46 in the tube l0. Figures 1 and '5adapt it to be carried in the pocket, vanity case, illustrate a slideplate 46 guided for movement U purse and the like. longitudinally of thetube In through the medium In the accompanying drawing: of guideflanges4B.

A small Figure 4 is an enlargedsectionaldetail viewof tube .54 also has its upper end secured to thethe air and fluid conduits; offset flange 56 of the slide plate and isslidably Figure 5 is an enlarged sectional view along the related to thetube 44. I provide the tube 54 with 16 line 5-5 ofFigure 2. an air bleed58, which air bleed is positioned '15 Figure 6 is a view similar toFigure 5 but i11usslightly above the upper end of the tube Mwhen tratingthe spray opening closed; 1 the slide plate 45 is positioned accordingto Fig- Figure '7 is a sectional view illustrating a liquid ures 1 and5, at which time the chamber is valve in its open position; and ventedto the atmosphere. 20 Figure 8 is a view similar to Figure 7 illustrat-When the slide plate 46 is moved downwardly 20 mg the valve in itsclosed position. of the tube Ill sufiiciently far to bring the head 55In the embodiment selected to illustrate my into sealing relation withthe opening in the shell invention, I make use of a tube Ill providedwith 32, vent opening 58 will be positioned inside the screw threadformations I2 for the reception of tube 40, and the latter tube fitstightly about the 5 a cap M provided with a seal l6 having pressure tube54 so as to provide liquid-tight relation relation with the end of thetube. Inside the therebetween. tube is a partition l8 which is locatedintermedi- Slide plate 45 is cut away at 58 to provide ate the ends ofthe tube in such manner as to accommodation for the shell 32, and thehead 50 provide a liquid containing chamber 20 and an is cut away at 60to accommodate the shell 32 air compressing chamber 22. Partition [8 haswhen the slide plate 46 is assembled with the tube 30 liquid-tightrelation with the tube ll]. 10. Valve tube 52 is provided with a plate53 Inside the chamber 20 I position a tube 24 having an opening forslidably receiving a valve which has its lower end spaced slightly fromthe stem 55 connected with a valve 51 arranged to partition [8 for theinlet of liquid to be sprayed. seat upon. the valve seat 59 below thebranch 28 Tube 24 may be welded to the tube Iii and has its to preventliquid from flowing into the branch 35 upp d eXtending through a p e dWa when the valve is closed. Between the valve 51 area 2 in the tube IDfor bringing e upp end and the flange 53 I interpose a compressionspring of the tube to a position exteriorly of the tube ill. BI, and theupper end of the valve stem 55 is Communicating with the tube 24 insidethe tube provided with an enlargement 53 which holds. the H1 is a bra ctube which includes a right valve stem 55 in assembled relation with theangular end 30 extending through the wall of the flange 53 when thevalve is opened according to tube lll, as illustrated in Figure 5. Tothe outer Figure '7. Figure 8 illustrates the valve in its face of t etube I0 I S a S pherical closed position, at which time the spring BI isshaped shell 32 having a spray opening 34. End flexed for firmly holdingthe valve against its 30 of the branch tube 28 communicates with theseat. 45 shell 32. In the chamber 22 I mount a piston 52 which An airtube 36 has one end extending through includes a leather or otherpliable sheet 64 the partition 18 and its other end extending clampedbetween plates 65 and 58, with the upwardly of the tube It to a positionslightly leather 64 of such diameter as to be foldable to above thebranch tube 28. This end of the tube provide a flange 10 fitting againstthe inner wall 50 36 is closed by a plug38. I connect a branch tube ofthe chamber 22. Plates 56 and B8 are held in 40 with the tube 36, whichbranch tube includes clamping relation upon the leather 54 by atuburight angular end 42 paralleling the end 30 and lar rivet 12 whichis fashioned at its inner end to extending through the wall of the tubeIll immeprovide a ball valve retainer 14, in addition to a diately abovethe end 30. End 42 also has comvalve seat 16. Flange 1D is held tightlyagainst 55 the wall of the chamber 22 by a split spring element 18.Figure 2 illustrates a compression spring 88 interposed between thepartition l8 and the piston 62 for urging the latter to the position ofFigure 2.

A tubular actuating member 82 is slidably related to the tube l8, andone end of the member 82 is closed at 84. Member 82 slides inside thetube [8 defining the chamber 22 and has its inner end bearing againstthe piston 62. I provide the member 82 with two longitudinal grooves 86,and the tube l8 may be depressed at 88 to provide lugs fitting insidethe grooves 88 to prevent complete Withdrawal of the member 82. However,the member 82 may be pressed inwardly of the chamber 22 against thetension of the spring 88, and the member will be returned quickly to theposition of Figure 2- when pressure is released from the member. Airvents 88 are provided in the member 82.

Member 82 may be provided with laterally extending grooves 92communicating with the grooves 88 for the reception of the depressedlugs 88 when the member 82 is shoved completely home and rotated aboutits longitudinal axis relatively to the tube l8. Thus the member 82 maybe supported substantially housed. inside the chamber 22 against thetension of the spring 88.

In operation, liquid in the chamber 28 is atomized through reciprocationof the member 82, which causes air to pass through the tube 38 andliquid from the chamber 28 to pass through the tube 24. Such air andliquid are admixed in the shell 32 and ejected therefrom in an. atomizedcondition through the orifice 34. The unit is of small proportions so asto facilitate carrying on the person, as in the pocket, purse or thelike. Chamber 28 is easily filled by merely removing the cap M. Member82 includes a knurled flange 94- Which facilitates manipulation,particularly when rotating the member to bring the lugs 88 into lockingrelation with the grooves 92. Slide plate 46 is provided with a spring96 having a bulge 98 arranged to have pressure relation with a rib I88formed on the outer face of the tube [8 so as to yieldingly hold thehead 58 in pressure relation with the shell 32 so as to preventaccidental shifting of the slide plate. The slide plate is humped I82 toprovide accommodation for the spring 96.

I claim:

Inan atomizer of the type described, a tubular member provided with apartition dividing the member into aliquid chamber and an aircompression chamber, a cap for closing the liquid chamber,the latterbeing provided with a nozzle, an air tube having an end communicatingwith the nozzle and its other end communicating with the air compressionchamber, a liquid conveying tube communicating with the liquid chamberand said nozzle, a piston operable in the air compression chamber forcompressing air into the air tube and through the nozzle, manuallyactuated means for operating said piston, a nozzle closing means movablyrelated to the tubular member, valve means associated with the liquidconveying tube, an air venting valve associatedwith the liquid chamber,and operating connections between the nozzle closing means and the valvemeans and the air venting valve for closing the same when the nozzle isclosed and vice versa.
